Abstract

The embodiment of the invention provides a method and a system for predicting a synonym tree for Chinese and English word pairs. The method comprises the following steps: acquiring a word pair to be predicted and a category synonym corresponding to the word pair to be predicted; and based on a known predefined source set, a semantic relationship set and the category semantic source corresponding to the to-be-predicted word, predicting the to-be-predicted word pair by adopting a predefined source tree generation algorithm to generate a semantic source tree. According to the embodiment of the invention, through the known synonym knowledge base, the category synonym information of the word pairs is given, and the synonym tree is predicted for the given word pairs, so that the automatic synonym tree prediction is realized, and compared with manual synonym tree labeling that a lot of time and cost need to be consumed, the method and the system have the characteristics of higher efficiency and higher accuracy.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a method and system for predicting sememe trees for Chinese and English word pairs. Background technique [0002] Sentences are composed of words, and different words have similarities and differences. HowNet is a widely used artificial annotation database, which is used to describe the semantics of different words. It marks words as a structure composed of a series of sememes, and sememes are smaller and indivisible semantic sets than words. It has a more basic meaning than vocabulary. HowNet and its labeled sememe information can be used in natural language processing tasks such as word disambiguation, sentiment analysis, cross-language word similarity, and word vector generation. [0003] Although sememes play an important role in natural language analysis and processing, manual labeling of sememes is a time-consuming and laborious task, and there are ine...
